string workspaceID

Header param: Optional header to select the Workspace for this request. The value is a Workspace ID (for example, wrkspc_011CZkZaBF1tNoB5wlCeusgy).

Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

Returns
class BetaManagedAgentsDeployment { Type; ID; Agent; /* 14 more */ }

A deployment is a configured instance of an agent — it binds the agent to everything needed to run it autonomously: an environment, credentials, initial events, and an optional schedule.
